To all whom it may concern:

Be it known that 1, JOHN H. FELT- HOUSEN, a citizen of the UnitedStates, residing at York, in the county of York and a State ofPennsylvania, have invented new and useful Improvements in TurbineTnstallations, of which the following is a specification.

This invention relates to turbine instal lations, and particularly to astructure providing for disposition of increased power turbine or wheelsin a flume, where the water flows in one direction, and havingrestricted dimensions which could not, practically,

be enlarged to receive theusual form of supply scroll. The turbine orwheel will be installed at a proper elevation for mini mum head, and therelativevelocities thereof are not affected by a change of head. theinstallation embodying the features 0 the invention, the water issupplied to the wheel gates from one direction and always fiows in thesame direction around and over the turbine and enters the turbine orwheel gates at difi'erent peripheral points with the same velocityrelatively to the number of wheel gates supplied. In other Words, eachhalf of the number of wheel gates is separately supplied with water atthe same velocity, so that the water supplied to the upstream half ofthe gates will not afi'ect the downstream half of the gates, or viceversa. The invention further contemplates an installation whereby withthe same head of water the inlet to the turbine, or wheelis effected atopposite points with uniform velocity relatively to the number of gatessupplied. More specifically and as a preferred organization involvingthe features of the invention, one or more parts of a complete scrollinlet or water supply may be used, but in all forms or changes thegeneral principle of operation is the same.

In the accompanying drawings, two forms of the installation areillustrated, and it will be understood that further variations instructure with the same general operation may be and are intended tobeadopted to accommodate differing fiume constructions wherein a highpower turbine is desired to be installed in restricted area that wouldnot permit the use of 8, complete supply scroll.

The numeral 5 designates a flume; 6 the runner on the one end of a wheelor power shaft '4'; 8 the wheel gates; and 9 the draft tube. The frameor enclosing casing for the turbine or wheel as shown is of the usualconstruction. All of these parts are well known and vention, being shownsolely to demonstrate the practicability of the features of the in- Theturbine installation illustrated by the drawings is also shown as formno part of the present inhaving a generator 10 directly connected to oroperatively associated with the turbineshaft, and gate operating meansconsisting of a shaft 11 attached to the usual gate ring, and actuatingmeans 12 is also shown, the generator 10 and actuating means beingdisposed on. a generator floor 13. The generator is not included in thefeatures of improvement, being illustrated simply to indicate thecomplete turbine structures or installations adopted in modernorganizations of this character.

Referring particularly to Figures 1, 2, 3 and 4, the essential featureof the invention in this-particular form thereof consists of a part of acomplete scroll inlet 14 fitted and secured to a part of the wheelcreasing as the number of gates decrease,

thereby maintaining the same relative velocities through the gates andto the wheel throughout the entire installation, and connected to aflange 16 of a tube 17 enclosing the shaft 7. The lower edge 18 of thescroll inlet rests on the bottom or bed of the flume and will besuitably braced and reinforced at all points to give the same therequisite strength. From the maximum elevation of the receiving end 15of this scroll inlet, the outer and inner walls 19 and 20 are determinedby the areas required inside the scroll from its receiving end 15 to itstermination 21, to supply one half of the number of gates in the wheelthe outer side 19 being convex and having a greater curvature than theinner concave side 20, the latter extending from a point near the centerof the wheel and trending outwardly over the top frame of the wheelenclosure and then approximately following the wheel periphery for ashort distance and terminating near the inner end of the baffle ordeflector 26, which excludes the flow of water rearward. A horizontalsupporting ledge or diaphragm 22 extends outwardly from the lower edgeof the inner side 20 and gradually converges in a curved line to thevertically reduced terminal of the inlet structure, said ledge ordiaphragm engaging the top portion of the wheel frame and servin also asa strengthening partition or guar within the body of the inlet. Asupporting or brace leg 23 extends downwardly from the ledge ordiaphragm 22 to the bottom or bed of the flume. The sides 19 and 20 havea top diaphragm or closure 24 which gradually slopes downwardly in aspiral contour and converges from the maximum elevated portion of thereceiving end 15 to the reduced end or terminal 21 of the inlet scroll.A vertical flanged casting 25 is se cured to the outer peripheralportion of the wheel casing and to one flange thereof the reduced end ofthe partial scroll inlet 14 is secured and sustained in rigidly appliedposition. To the remaining flange of this casting the rear end of aconcave baflle or deflector 26 is secured, the opposite en 1 of saidbafile or deflector being connected t the adjacent side or enclosingwall of the flume. This baflie or deflector extends upwardly to the topof the wheel'casing or housing to prevent the water from passing intothe wheel at a point that would result in retardation of the operationof the wheel runner.

The opposite sides of the flume as shown are parallel and resumably insuch relation to adjacent umes or other structures as to preclude thepractical widening thereof suflicient to permit introduction of theusual full scroll inlet as indicated in dash lines 27. Hence, to meetthis obstacle and provide for the installation of a high power turbineis the purpose of the improvement thus far described, and theimprovement, as heretofore indicated, prevents the least retardation ofrotation of the wheel runner by counteracting water influence suppliedto a portion thereof that might otherwise be exposed. It will also beunderstood that the wheel with the improvements is fully submerged, anda part of the water enters a part of the wheel gates as indicated by thefull and dotted line arrows 28, and a part enters the receiving end 15of the partial scroll inlet and takes the course indicated .by thedotted arrows 29 and in the direction of rotation of the wheel. Thewater entering the partial scroll inlet, in view of the construction andcontour of the latter has the same volume and velocity relatively to thenumber of gates it supplies throughout its entire course through thesaid inlet. y

In the form of the improvement shown by Figures 5, 6 and 7, partssimilar to those heretofore specified are designated by similarreference characters, and the structural diflerence resides mainly in adouble partial scroll inlet consisting of two partial scroll units 30and 31 in reverse positions, and usable with water continually flowingin one direction thereto and over the same.

This second form of the improvement is shown produced by the use ofconcrete or cement material in the flume, the wheel being disposed in acentral space 32 formed in the opposing portions of the contiguouslyarranged units 30 and 31. Each of these units 30 and 31 is hollow andhas a scrolllike interior contour continuing regularly from maximumdimensions at the inlet 33 thereof to the terminal 3 1 of minimumdimensions. The inlet of the unit 30 faces the direction of flow of thewater, and the inlet of the unit 31 is in the rear and receives thewater thereinto in a forward direction, the entrance of the water intothe inlets of these 'units being clearly indicated by the arrows 35 and36 and which show that the water enters the wheel gates at all pointsaround the wheel periphery in the direction of rotation of the wheelrunner. The water, always flowing in the same direction, enters thewheel gates at opposite points with pro ortionate volume and uniformvelocity re atively to the number of wheel gates supplied, so that thereis no retardation in operation of the wheel at any part thereof, withthe advantageous result that the full power of the water flowingcontinually in one direction to and over the units 30 and 31 and theWheel is conserved within the restricted dimensions of the flume whichwill not permit an enlargement suflicient for installation of the usualcomplete scroll supply structure. The same principle is involved in thissecond structure as in that first described, namely, the water flowingdownstream supplying the upstream half of the gates and a part of thewater flowing over the turbine wheel and entering the wheel in a reversedirection and supplying the remaining half of the gates withproportionate volume and uniform velocity relatively to the two halfgate series supplied, and thereby avoiding a counteracting influence ofthe water operating on the onehalf series of gates relatively to theremaining one-half series of gates.

The second form of the improvement involving the two partial scrollunits in opposition is shown formed of concrete or cement, but it willbe understood that these units may be otherwise produced or be formed ofother material. As an incidental feature, a cover or partition plate 37is applied above the wheel space or seat defined between the units 30and 31, to prevent the water from eddying or churning over and adjacentto the top of the wheel casing or housing.

Though the two forms of installations em- 'bodying the features of theinvention have 7 been described as specially adapted for disposition ina flume wherein the water continually flows in one direction, it isproposed to install the partial scro-ll' supply means either in itssingle or double form. as

hereinbefore explained and in reasonable and permissible equivalentforms in other water supply flumes or the like wherein the water may notflow in one direction and to which the improvements may be operativelyapplicable.

What is claimed as new is 1. A turbine installation for awidth-restricted flume, comprising a submerged turbine having a sideinlet with controlling gates and rotatable driving means therein,

and water inlet directing and flow controlling means operativelydisposed relatively to and completely enclosing part of the side inletof the turbine to supply the water to one-half groups of the drivingmeans and thereby proportionately supply water to all parts of thedriving means to regularly rotate said latter means in one direction andpreventing water from entering the turbine at any point in a directionopposed to the direction of rotation of the driving means.

2. A turbine installation for a width-re-.

stricted flume, consisting of a turbine submerged in the flume andcomprising gates for controlling entrance of water thereinto and to arotary driven means, and water enclosing and confining supply means andapplied over and entirely enclosing a portion of the periphery and gatesand controlling separate supply of water to different peripheralportions and gates of the turbine to engage and operate the rotarydriven means regularly in one direction with the same velocityrelatively to the number of gates supplied and also excluding entranceof water into the periphery at any point in a direct-ion that would havea counteracting influence on the rotary driven means.

3. A turbine installation for a width-restricted flume, comprising asubmerged turbine having a closed top and side inlet and controllinggates and rotatable drivin means therein, and water inlet directing andflow controlling means extending outwardly beyond the periphery of theclosed top over a portion of the side inlet to provide a scrollstructure of less extent than the usual structures of this type tosupply the water to onehalf groups of the driving means and therebyproportionately supply water to all parts of the driving means toregularly rotate said latter means in one direction and preventing waterfrom entering the turbine side inlet at any point in a direction opposedto the direction of rotation of the driving means.

In testimony whereof I have hereunto set my hand in'presenc'e of asubscribing witness.
